Is anyone else getting cold/sick much more often these days?

No, I feel about the same. If anything slightly healthier.

I didn't work from home much though. Currently writing this from the pub.

you might be getting old, you are no longer that young that you used to be 3 years back

I’m getting sick less often, possibly because of still masking in public indoor spaces, or maybe because I began exercising more since the lockdown. I haven’t had Covid (at least not to the extent of symptoms or positive test).

No, far less for me.

2000-2019: unwell (flu, cold) 2-3 times a year. 2020-2022: not unwell a single time, 36 months counting now.

Context: I now travel on public transport once a month vs 20 times a month. I work from home and not a busy office with meeting rooms. I socialise less. I exercise less (I walk less per day). I eat about the same quality. I sleep more. I get less sunlight. I'm happier.

My view: it's all down to much reduced exposure to the poor hygiene that the public practice. Whether or not there is "more of it about", I'm only exposed 5-10% as much as I previously was.

Sleep more. Go camping and try and run in areas with lots of trees. I find I get more sick the more I'm indoors working at a computer. Which is my full time gig, so I have to make an effort to balance it out and be outside and getting into nature.
